C# 如何在C中从数据库中选择下一行？

这是代码，我已经试过了，但它不起作用

不公开； 字符串sql=SELECT*from bills order by sr_无偏移10行； cmd=新的OleDbCommandsql，con； dr1=cmd.ExecuteReaderCommandBehavior.CloseConnection； dataGridView1.Rows.Clear； 而dr1.Read==true { dataGridView1.Rows.Adddr1[0]，dr1[3]； } con.关闭； 使用偏移和提取：

SELECT col1, col2, ...
FROM ...
WHERE ... 
ORDER BY -- this is a MUST there must be ORDER BY statement
-- the paging comes here
OFFSET     10 ROWS       -- skip 10 rows
FETCH NEXT 10 ROWS ONLY; -- take 10 rows

我强烈建议您了解数据绑定，它有一种更有效的方式来显示数据

SELECT col1, col2, ...
FROM ...
WHERE ... 
ORDER BY -- this is a MUST there must be ORDER BY statement
-- the paging comes here
OFFSET     10 ROWS       -- skip 10 rows
FETCH NEXT 10 ROWS ONLY; -- take 10 rows
